Dr. Jorge Vivanco

Dr. Jorge Vivanco is a Professor in the Department of Horticulture and Landscape Architecture at Colorado State University. He received a B.S. degree in Agronomy from the Universidad Nacional Agraria La Molina in Lima-Peru, and a Ph.D. in Plant Pathology from The Pennsylvania State University.  He joined CSU in 2000 to start a program on root biology and the interactions of roots with surrounding organisms.

The primary responsibility of Dr. Vivanco’s program is to develop knowledge on root-microbe interactions related to horticultural crops that could lead to new agricultural technologies and applications.  His program interacts with stakeholders such as horticultural producers and companies interested in this scientific space to create the next generation of products and technologies in agriculture.  In addition, knowledge derived from this program is disseminated to the potato growers in the San Luis Valley of Colorado, as well as to horticultural producers in Colorado and abroad.

Dr. Vivanco’s laboratory has published extensively on these topics (133 research papers) and he has edited two books. His current research focuses on the interactions of roots with the soil microbiome. Recent research suggests that roots can culture specific microbes and microbial functions depending on the stage of development and needs of the crop.  Teasing apart these observations through continued experimentation will catalyze the next agricultural revolution – one that promotes sustainability. This agricultural awakening will involve utilizing the full genetic potential of a crop to promote soil microbial diversity, health and resilience.

Dr. Vivanco interacts closely with the scientific community as a reviewer of scientific publications, research grants and as an Associate Editor of the journal Microbial Ecology. On December 18th, 2014 he was invited to attend a round table discussion in the Office of Science and Technology (OST) of the U.S. White House.  The purpose of this meeting was to initiate discussions to educate the OST on the science, applications and policy related to The Microbiome.  The associate director of this office had weekly meetings with President Obama and wanted to bring this topic to his attention for further development, which is currently ongoing.  Dr. Vivanco has taught the graduate course Roots and Rhizosphere Biology and currently teaches Medicinal and Value Added Uses of Plants.

Dr. Vivanco is married to Dr. Tiffany Weir (Associate Professor of Food Sciences at CSU) and has two sons: Jorge and John. He and his family enjoy travelling to new places to experience new cultures and food.

Mike DiLegge

Mike DiLegge is a researcher in the CRB with a bachelor of sciences degree in Horticultural Food Crop Production and a minor in Botanical sciences. Mr. DiLegge has experience in both field crop and wholesale floriculture production operations, in both greenhouse as well as in field system facilities in White Marsh, MD. In the CRB, Mr. DiLegge’s research focuses are on biological control organisms for the Columbian root-knot nematode, as well as the effects of soil sterilization and plant root exudates on plants ability to acquire beneficial natural soil microbiota from the environment.

Qinggang Guo

Dr. Qinggang Guo, is a professor visiting from the Plant Protection Institute;  Hebei Agricultural and Forestry Science, in Baoding, China. He received his doctor degree in China Agricultural University in 2007. Now, as a visiting scholar in the Lab of Dr. Jorge Vivanco, he is working on the ecological mechanism of Plant Growth-Promoting Rhizobacteria (PGPR). His research interests are focused on the ecology and molecular genetics of biocontrol agents, especially for the members of Bacillus genus.

Hugo A. Pantigoso

Hugo is a graduate student at the Horticulture Department at CSU since 2017, and a Research and Teaching Assistant (Hort-100 and Hort-401). His research focus mainly on plant-bacteria interaction in the rhizosphere and root secretion influenced by synthetic fertilization. Hugo has been involved in plant research since 2012 in diverse positions in academia and industry involved in the planning, design and execution of research trails on laboratory, greenhouse and field, in a wide range of fruits and vegetables crops. Hugo is an Agronomist with strong background in integrated crop management, plant diseases and soil microbiology. He graduated from Valle Grande in 2009 (Peru) and Zamorano University in 2013 (Honduras). Hugo is interested in cultivated plants as blueberry and potato, but not limited to.
